Abstract

Abstract: This paper introduces the basic design of suction-type sea cucumber fishing device and its performance evaluation calculation method. According to the specific requirement and actual situation of sea cucumber fishing, the unique structure design of suction-type fishing method is proposed. Based on CFD method, the resistance of the device under water is predicted, and the internal and external flow field of the sea cucumber fishing device during underwater navigation and suction fishing are simulated interactively. Through the numerical simulation of the flow field inside and outside the device, the resistance of the device is evaluated to measure whether the propulsion force of the propeller can match the operation. Through the analysis of sediment suction, the suction force matching the device is calculated to improve the performance and reliability of the device.
